Inventor: DELANEY FRANCIS ALFRED

Filed: 1979-05-30
Abstract: A bottle closure comprises a valved insert comprising a housing 11 and a valve member 17 which is initially biassed by a spring 18 into a closed condition. Insertion of a measure dispenser spigot moves the member 17 into an open condition. Removal of the spigot, causes the member 17 to move into a closed condition. The member carries a spindle 30 which co-operates in pawl and ratchet manner with pawls 32 which prevent movement into the open condition. This pawl and ratchet detent is initially ineffective since the pawls are held out of co-operation by a bush 31 which is a tight frictional fit on the spindle and during an opening movement is held so the spindle slides through it but on a subsequent closing movement is held by the spindle and drawn out from the pawls so releasing them. Thus the bottle cannot be re-used once on a measure dispenser. 
     Other embodiments show a valve member co-operating with other movable parts to form a sleeve valve which is initially locked open by a detent but closes as a result of an initial opening movement and subsequent closing movement. 
     Various refinements are shown.

Abstract: The invention relates to shower fittings especially those used in the paper and board making industries. The shower fitting incorporates at least one jet for directing on to a surface a jet of liquid which is suitable for cleaning and/or reconditioning the surface. The jet or jets are normally mounted in a tube to which the liquid is supplied and which is reciprocated across the surface to ensure that the entire width of the surface is treated and to avoid damage to the surface that might result if a jet of liquid is directed constantly at the same area of the surface.The invention is concerned with the problem of ensuring adequate support and protection for the tube.In one particular embodiment, the tube 1 is mounted for reciprocation inside a support tube 3. Support bushes 2 spaced along the axial length of the tube 1 ensure adequate support whilst protection is provided by the outer tube 3. The tube 1 carries a plurality of jets 7 and the outer tube has a slot 13 aligned with the jets 7 to allow liquid emerging from the latter to reach the surface. Driving means for example an hydraulically-actuated motor 10 is mounted at one end of the outer tube 3 and is connected to the inner tube 1 to reciprocate the latter.Treatment liquid is supplied to the inner tube 1 via one end thereof.

Abstract: An impedance controller is used for controlling electrode-to-bath spacing in an arc furnace. Measured quantities proportional to the electrode voltage and the electrode current are determined and an actual impedance value is formed from the measured values by means of a divider. The actual impedance value is compared with a predeterminable desired impedance value to derive a control signal. If in the event of a short circuit, the actual impedance value reaches a predetermined lower limit, a switching element sets into the controller a signal causing full drive, so that the electrodes are raised at maximum velocity. If the sum of the two measurement quantities becomes zero, the output of the controller is cut off.

Title: Timepiece comprising a division ratio adjustable divider chain
Inventor: DELLEA MARIO
IPC: G04G3/02
Filed: 1981-11-25
Abstract: The timepiece includes a low frequency oscillator serving as time base and arranged to feed a first chain of frequency dividers having an adjustable division rate in order to display the time and a high frequency oscillator feeding a second chain of frequency dividers. During an imprecise period established by the first chain (3) reference pulses from the second chain (7) are counted thereby to establish a binary value (HF-DF) representing the amount of imprecision of the first chain in respect of the reference. This value is transferred into a memory in order to correct directly or indirectly the division rate of the first divider chain. There is thus obtained an oscillator having the stability of a high frequency oscillator but with energy consumption only slightly exceeding that of a low frequency oscillator.

Abstract: To make diapers having elasticized regions, unstretched segments of elastic ribbon (37, 38) are deposited on a first rotating roll (35) which has vacuum holes in its periphery for attacting the body of a segment and a mechanical element (57) for temporarily securing one end. The first roll rotates segments successively to a place adjacent a second roll (51) which has a larger radius and, hence, higher peripheral velocity than the first roll. The second roll has grippers (90), (92) spaced apart by an amount substantially equal to the desired stretched length of the segments. The leading end (39') of each segment on the first roll is engaged by a gripper (90) on the second higher speed roll so the segment stretches after which a lifter (52) on the first roll releases the trailing end for it to be engaged by a gripper to hold the stretched segment on the second roll. Quick setting glue (101) is applied to the stretched segments and the top porous sheet material (103) comprising the diaper is run in contact with the segments to pick them up. The exposed faces of the segments have glue applied and the sheet is superposed on a moving non-porous backing sheet on which absorbent pads have been deposited and a continuous diaper web is formed. The web is cut transversely (118) and remotely from the segments and individual diapers are formed.
